Please please help help me please please help help!!!!!

Answer:10 liter * 20%= x liter*40% + (10- x) liter*5%

10l * 20%= x liter * 35% + 10 liter*5%

x liter *35 = 10l * 20 - 10l *5= 10l*15

x liter = 10l *15/35= 4.28 L= 4.3L

The volume of 40% solution= 4.3L

The volume of 5% solution= 10L- 4.3L= 5.7L

Step-by-step explanation:

In this question, you want to make 10 liters 20% concentration solution by mixing 5% and 40% concentration. There should be multiple answers to this question. Assuming that the total volume of 5% and 40% solution equal to 10L(no solution wasted), then you can determine the volume of solution needed. The formula should be:

Answer:

No

Step-by-step explanation:

The given inequality is b < 1.  We determine whether or not b = 5 is a solution by substituting 5 for b and asking ourselves whether the resultant inequality is true or not:

5 < 1 is FALSE and so b = 5 is NOT a solution of the given inequality.

Answer:

0.56 inches from the vertex of the canvas

Step-by-step explanation:

Golden ratio can be interpreted as

B / A = ( A + B ) / B ----- (  1  )

A = smaller side = 12 inches

B = larger side  = 16 inches

Back to equation 1

16 / 12 = ( 16 + 12 ) / 16

4 / 3 ≠ 7 / 4

The Golden ratio can not be applied because the rule is not obeyed  

The focal point can be determined as :

( longest width / 2 )= 12 / 2 = 6^ 2 = 36 ---- 2

(4* depth) = 16 * 4 = 64 ---- 3

hence the focal point ( 2 / 3 ) = 36 / 64 = 0.56 inches from the vertex of the canvas

Answer:

Eve is 8, 10 in 2 years and peter is 18, 20 in two years

Step-by-step explanation:

26/2=13

Eve = 13    Peter=13

Then just keep subtracting from eve then adding that on to peter. Then add two years everytime for the age they will be in two years

And yh it is basically trial and error

sorry if you get the explanation

1/2 din 5 €

Step-by-step explanation:

Opțiunea 1

1/4 din 5 €

= 1/4 × 5 €

= 1,25 €

Opțiunea 2

1/2 din 5 €

= 1/2 × 5 €

= 2,5 €

Prin urmare, opțiunea care ar însemna mai mulți bani este 1/2 din 5 €

Answer:

44.1 degrees

Step-by-step explanation:

In this diagram we are given the hypotenuse (39) and the side adjacent to the angle x.  The cosine function relates the hypotenuse and adjacent side as follows:

cos x = 28/39

Using the inverse cosine function on a calculator, we get x = 0.7699 radian, which converts to degrees if we multiply this result by 180/π:

Angle x, in degrees, is 44.1 degrees, which is to the nearest tenth.

Answer:

x = 3, y = 1

Step-by-step explanation:

If your question is this: 2x + 4x + 8y + 16y = 42

6x + 24y = 42

3x + 12y = 21

For x and y are positive integers, there is only 1 set of x = 3 and y = 1 is the solution  (because x = 7 and y = 0 is excluded)

check: 6 + 12 + 8 + 16 = 42

Answer:

x=2

Step-by-step explanation:

1. AB=AC (The triangle is isosceles. This means that at least two of its sides are equal in length. Looking at the triangle in the picture, sides AB and AC look the same, so we will assume that they are equal. Note that as you get more advanced, assuming isn't the best strategy. You should always try to look for hints if you are ever unsure. For example, if there are two angles that are the same measure in a triangle, the two sides that are only touching one of these angles are equal in length. This is called the base angles theorem converse.)

2. 9x-3=6x+3 (Rewrite sides AB and AC as the values given in the picture. This is called substitution.)

3. 9x=6x+6 (Add 3 to each side)

4. 3x=6 (Subtract 6x from each side)

5. x=2 (Divide each side by 3)
